Abstract
Disclosed is a combustible gas leakage proof system used on a two-stroke engine. The utility model is characterized in that a pressure ring is arranged at the skirt of a piston and a one-way valve is arranged at the exhaust vent. The combustible gas leakage proof system of the utility model can prevent the combustible gas from leaking from the exhaust port when the piston moves downwards and compresses combustible gas in a crankshaft tank and can also prevent the combustible gas from leaking from the exhaust port during the scavenging process. It is tested that oil consumption is reduced from 2.15L/hundred KM to 1.75 L/hundred KM, reducing by 19 percent, thus reducing air pollution.
Description
Technical field
The utility model relates to a kind of energy conserving system of two stroke engine.
Background technique
At present, known two stroke engine has the part combustible gas and scans out from relief opening when scavenging, in descent of piston compression crankshaft case, also have the part combustible gas during gas and release from relief opening, thereby cause the oil consumption height, pollute big.
Summary of the invention
The purpose of this utility model provides a kind of two stroke engine combustible gas leak prevention system, when it can prevent scavenging and descent of piston when compression combustible gas discharge from relief opening, thereby reach purpose of energy saving.After tested, the gasoline consumption is reduced to 1.75 liters/hundred kilometers by 2.15 liters/hundred kilometers, has reduced by 19%, pollutes simultaneously and also declines to a great extent.
Technological scheme
The purpose of this utility model is achieved in that the top of piston is equipped with the twice compression ring, and the skirt section is equipped with that one compression ring exhaust ports be equipped with can only be to the reed one-way valve of external-open.
When in the descent of piston compression crankshaft case during gas since the sealing combustible gas of skirt section compression ring just can not release from relief opening by the gap location of piston and cylinder, when scavenging, close owing to leaf valve, combustible gas can not scan out from relief opening yet, when combustible gas outburst exhaust, high pressure air cognition is backed down leaf valve automatically and is discharged from relief opening, the exhaust terminal hour, air pressure reduces, and leaf valve cuts out automatically.
Because adopt such scheme, this combustible gas leak prevention system can reduce fuel consume, reduce to 1.75 liters/hundred kilometers through actual measurement gasoline consumption by 2.15 liters/hundred kilometers, descended 19%, pollute simultaneously and also decline to a great extent.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an embodiment of the present utility model.
Among the figure: compression ring on 1; 2 lower air rings; 3 skirt section compression rings; 4 pistons; 5 relief openings; 6 scavenging ports; 7 cylinders; 8 reed one-way valves.
In Fig. 1, have in the cylinder (7) of scavenging port (6) piston (4) is housed, compression ring (1), lower air ring (2) and skirt section compression ring (3) are housed on the piston (4), sheet one-way valve (8) is housed in the relief opening (5).
Claims (2)
1, a kind of two stroke engine combustible gas leak prevention system is equipped with the twice compression ring on the top of piston, and it is characterized in that exhaust ports is equipped with can only be to the reed one-way valve of external-open.
2, two stroke engine combustible gas leak prevention system according to claim 1 is characterized in that the skirt section of piston is equipped with compression ring.
